The Stovebolt Site Forums The Shop Area Engine Shop Deciphering my Rochester B

I have a 48 1.5 ton with a 235 and a Rochester B carb. As far as I know everything is original to the truck. I am trying to decipher the Model number of my carb It appears to be 7084518 C or 7004518 C.
I have had no luck in matching these numbers to various sources on the web.
The other numbers are 22712 on the on the throttle/choke linkage, and 60 or 09 on the air horn portion.
Any advice or suggestions on what carb kit is the most appropriate?

I emailed the same pictures that I have linked above to the Carburetor Shop, seeking a rebuild kit.
This was their response "These units are identified by tag only. Once the tag has been removed, virtually impossible to identify. Regards."
I rebuilt this carb a couple years back with a Napa kit for some version of the Rochester B. I am trying to find the old rebuild kit box for a part number. Regardless the carb seemed to run great, after I rebuilt it. Now that I have fixed my intake/exhaust/heat-riser issues, I feel another rebuild is in order. If you have any suggestions of which 'basic" kit I should get or any major differences in the kits please let me know.
Thanks
